ABOUT MARK
I became an entrepreneur by buying a business. Running it became the real education.
My background began in finance and accounting. I later became interested in entrepreneurship through acquisition and eventually acquired the business I now operate.
I don’t write because I believe I have all the answers. I write because documenting what works, what fails, and what changes my thinking may be useful to others.
